Abstract :
The critical problem of locating a periodically embedded frame synchronization pattern in random data is considered for direct-detection on-off keying (OOK) optical systems. Results of simulation studies on several synchronization schemes are presented. Performance results of comparisons with the maximum-likelihood (ML) estimate rule over a wide range of signal-to noise ratios (SNR) are provided. It is demonstrated that the modified high signal-to-noise ratio (HSNR-1) rule described by Asgill (1990), yields results that closely approach that of the ML rule
